seems to save some of the subunits in PDB format that I was able to import into Maya. It does save the whole structure as obj, but this file format is not compatible with the import plugin mMaya. I was wondering if there is a way of selecting a number of chains
simultaneously and then saving those in a PDB and repeating until the whole capsid is saved out and then reconstruct in Maya? There are a very large number of chains and I seem only able to select one at a time from the drop down menu. Alternatively, can you
save as emd files from ChimeraX?<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">Hi Elaine,<br>
<br>
It's me again! Hope you had a nice weekend...<br>
<br>
I'm having some trouble downloading the HIV capsid file, PDB 3j3q. When I try to import it to Chimera it begins downloading, but the molecule never quite appears, even though it ends up in the entry list. The screen stays blue like it has yet to be uploaded.
If I try to upload it from the list, again, nothing appears. I realise the molecule is very large, but I think I'm missing something important here?<br>
<br>
Thanks so much for your help, as always,<br>
<br>

<p class="MsoNormal">Depending on what you’re trying to do with this capsid, maybe you could try using ChimeraX instead of Chimera. It handles large structures much more efficiently, but it does not have the same set of features as Chimera.<o:p></o:p></p>
